VLAN problems with pix

jdedon
Level 1
Level 1

I have a pix with failover.

I have one interface vlan903 physical (no host)

I have two logical vlan900 and vlan902. (contain hosts)

Each pix has a ethernet cabled connection to a 6509.

Both switch ports on the 6509 are configured as dot1q trunks. They are native to vlan 903.

Now, there was a failover that appears to be associated with the interface with the physical vlan.

I look at sho fail and all three vlans show normal /waiting on both pix.

Traffic is still reaching the two logical vlans.

I can ping each vlan interface from either pix except for the physical vlan interface.

I can ping the local vlan903 address on each pix but not accross vlan 903.

I tried a cross-over cable from my laptop to the standby pix and do not get a response to ping.

The primary is production, so I can do this test.

I added another port on vlan 903 on the 6509 and put my laptop there and can not ping either pix on that vlan.

Both interfaces on the 6509 sho connected trunk

I can't figure out what is bad here.

I failed it back last night and after a short while it failed over again. Basically saying that the mate was healthier for this interface.

Here is the config and the sho fail

Hi,

can you try to change the native vlan of the switches to vlan 1 or any vlan other than 903

thanks
